VII.—A Piece or Pawn touched must be played, unless at the moment of touching it the player say “J’adoube” or words to that effect; but if a Piece or Pawn be displaced or overturned by accident, it may be restored to its place.
VIII.—While a player holds the Piece or Pawn he has touched, he may play it to any other than the square he took it from; but, having quitted it, he cannot recall the move.
IX.—Should a player take one of his adversary’s Pieces or Pawns, without saying “J’adoube” or words to that effect, his adversary may compel him to take it; but if it cannot be legally taken, he may oblige him to move the King; should his King, however, be so posted that he cannot be legally moved, no penalty can be inflicted.
X.—Should a player move one of his adversary’s men, his antagonist has the option of compelling him—1st, to replace the Piece or Pawn and move his King; 2d, to replace the Piece or Pawn and take it; 3d, to let the Piece or Pawn remain on the square to which it had been played, as if the move were correct.
XI.—If a player take one of his adversary’s men with one of his own that cannot take it without making a false move, his antagonist has the option of compelling him to take it with a Piece or Pawn that can legally take it, or to move his own Piece or Pawn which he touched.
XII.—Should a player take one of his own men with another, his adversary has the option of obliging him to move either.
XIII.—If a player make a false move, i. e. play a Piece or Pawn to any square to which it cannot legally be moved, his adversary has the choice of three penalties; viz., 1st, of compelling him to let the Piece or Pawn remain on the square to which he played it; 2d, to move correctly to another square; 3d, to replace the Piece or Pawn and move his King.
XIV.—Should a player move out of his turn, his adversary may choose whether both moves shall remain, or the second be retracted.
XV.—When a Pawn is first moved in a game, it may be played one or two squares; but in the latter case the opponent has the privilege of taking it en passant with any Pawn which could have taken it had it been played one square only. A Pawn cannot be taken en passant by a Piece.
